The U.S. parks honcho who supervises the Statue of Liberty and Ellis Island charged last night that she and her husband were viciously beaten by federal cops she oversees after a racially motivated traffic stop.

National Parks Service Superintendent Diane Dayson said the assault came as her husband’s arrest turned into a brawl that spread to their home in Staten Island’s Fort Wadsworth on Monday morning.

Dayson – who made history seven years ago as the first black woman to land the prestigious job of overseeing New York’s most famous tourist sites – told The Post the attack resulted from long-simmering disputes over everything from bigoted police officers to government turf battles.

She said the incident left her husband, Kevin, 50, with severe bruises and swollen eyes and herself badly shaken, with injured hands and wrists.

“I can’t believe I was handcuffed . . . and taken to jail” by the parks cops, Dayson said.

“Ultimately, I’m the one they report to.”

“I’m supposed to be a model citizen . . . and I was slammed into by [U.S.] Park Police, and my husband was beaten by Park Police with a nightstick and had an entire can of pepper spray emptied into his and my dog’s eyes. I’m in total shock.”

Dayson said her husband was “racially profiled” by a cop with a history of harassing her family.

She said the officer tried to stop him to check ID around 10:50 a.m. near their home, but her angry husband wouldn’t stop his car until he got to the house. A fight ensued, other officers were called and they all wound up crashing into the dwelling, she said.

But a spokesman with the U.S. Park Police defended the cops’ actions, saying the dispute stemmed from a “routine” traffic stop.

Kevin Dayson, a self-employed consultant, was charged with assaulting an officer, resisting arrest, obstruction of governmental functions and driving with a revoked license and no seat belt, Park Police Sgt. Scott Fear said.
